The Erbium:YAG laser is able to remove a very thin layer of skin making it possible to treat even delicate areas, or with multiple passes, ablate deeper into the skin or unwanted skin lesions. We can now perform a light “laser peel” with a quick recovery period or full-thickness resurfacing for deeper lines when used in conjunction with the CO₂laser. This laser is often used to smoothe the skin after mole biopsy and removal.
